Question
Is it possible to obtain a IQ/OQ validation certification for HQd Meters/Intellical probes?
Summary
IQ/OQ validation certification for HQd meters and probes
Answer
No. Since these are digital meters, it is not possible to verify the meter and probes' results are correct independently. It is not possible to check the mV readings from the sensor, since the readings are converted to digital signals within the probe. It is not possible to verify how the calculation is made inside of the meter without having an Intellical probe connected to the meter.
